Today's interesting fact has to do with diet. Mostly because I'm constantly told to diet, but partially because we have been told that our ancient ancestors ate mostly meat and vegetables, without foods that are high in carbohydrates. This impression seems to have come about because archaeologists in the past have been too diligent to clean and sterilise both the tools they used as well as the artefacts they have found, without checking the embedded plant materials within or on the surface.

When I was a child, the scout troop I belonged to used to go on survival hikes. Our scout masters had made arrangements with certain farmers for the use of their woods and fields in our search for food. We were required to only find wild forage, and not allowed to raid local crops. We spent our time, searching for wild food which consisted of, roots, berries, fungus, leaves and the like, then preparing it what we found, getting it ready for our three meals. While we were taught how to create snares and traps, except for catching fish, we were not allowed to use what we had learnt for getting meat. Instead, we would be provided with a certain amount of eggs and meat, which were kept refrigerated by our scout masters and doled out every morning and evening to have with what ever we had found in the surrounding forests and fields.

One of the foods we ate, on a limited basis was the root of bull rushes, which we called Cattails. When foraging, you must be careful to leave enough behind to feed wild animals as well as to continue successful survival of the food source. The American Indians supplemented their diet with Cattails, drying the roots, then grinding them to create a flour, before making bread which was baked in fires and small bread kilns. The flour produced is high in carbohydrates and makes a bread that tastes very good to a small boy who has spent the day making the flour.

Recently in Italy, Russia and the Czech Republic archaeologists found grindstones, that by identifying the plant material embedded on them were used to create flour from the roots of rushes and ferns. From the remains, these grindstones have been dated to have been last used over 30,000 years ago. So our European ancient ancestors were making flour and as other fragments confirm, bread. Instead of having just mastodon burgers and veggies, they may have even put their meat between two slices of bread. Which could put the sandwich's invention many thousands of years before the Earl of Sandwich thought of it.
